Get better sound in minutes
Short, practical walkthroughs for the things people do most with SoundBooster.
1. Make a quiet video louder
- Install the Chrome extension and pin it to your toolbar.
- Open the video and start playing it.
- Click SoundBooster → 150% Boost. Still too quiet? Try 200% Loud, then drag higher if needed.
- Keep the limiter on. If voices sound harsh, lower the boost or reduce Treble in Advanced controls.
- Turn on Remember for this site to use the same level next time.
2. Make dialogue easier to understand
- Boost the tab, then open Advanced controls.
- Choose the Quiet dialogue profile. It lowers rumble, lifts the 1–3.5 kHz range where speech is clearest and narrows the stereo image.
- Fine-tune the 3.5k EQ band until voices sit clearly on top of music and effects.
3. Master a song for streaming
- Open AI Mastering and drop in your final mix (WAV if you have it).
- Pick a starting profile — Balanced is a safe start.
- Type what you want, for example “Keep the dynamics but add more clarity”, and press Master My Track.
- Switch between A and B with loudness matching on. If the master only sounds better because it's louder, it isn't better.
- For Spotify and YouTube, set Loudness target to about −14 LUFS; they turn louder tracks down anyway.
- Export 24-bit WAV for distribution, or MP3 320 kbps to share.
4. Match a reference track
- Open Reference Mastering. Add your mix and a file of a song with the sound you want.
- Compare the tonal balance chart: where the reference line sits above yours, it has more energy in that range.
- Press Apply Reference. Start around 60–80% match amount; 100% can overshoot.
- Listen to all three versions with level matching on, then export.
5. Check your loudness before release
- Open the LUFS Meter and load your master.
- Read integrated loudness and true peak. For most platforms, keep true peak at or below −1 dBTP.
- Use the Loudness Range Analyzer to see how dynamic the track is.
6. Make an instrumental
- Open the Vocal Remover.
- With the AI server connected, choose AI model for the cleanest result. Otherwise use On-device, which works on stereo mixes with centred vocals.
- Download the instrumental stem, or rebalance the stems and export the mix.
